Paper Abstract

We have studied and analysed in this paper, the modeling of single-walled carbon nanotubes (SWNTs) optical and electrical properties utilizing terahertz (THz) time-domain spectroscopy in the frequency range of 0.1-2 THz. We have compared the measurement data of the THz power absorption coefficient, index of refraction and conductivity of SWNTs film with the experimental results obtained in Ref. [9], being our results based on the combination of Drude- Lorentz and Maxwell-Garnett models. Since we suppose the SWNTs network as an effective medium embedded in air, the comparison shows good agreement.
